+=head1 NAME
+
+mutt-notmuch - notmuch (of a) helper for Mutt
+
+=head1 SYNOPSIS
+
+=over
+
+=item B<mutt-notmuch> [I<OPTION>]... search [I<SEARCH-TERM>]...
+
+=item B<mutt-notmuch> [I<OPTION>]... thread < I<MAIL>
+
+=back
+
+=head1 DESCRIPTION
+
+mutt-notmuch is a frontend to the notmuch mail indexer capable of populating
+maildir with search results.
+
+=head1 OPTIONS
+
+=over 4
+
+=item -o DIR
+
+=item --output-dir DIR
+
+Store search results as (symlink) messages under maildir DIR. Beware: DIR will
+be overwritten. (Default: F<~/.cache/mutt_results/>)
+
+=item -p
+
+=item --prompt
+
+Instead of using command line search terms, prompt the user for them (only for
+"search").
+
+=item -h
+
+=item --help
+
+Show usage information and exit.
+
+=back
+
+=head1 INTEGRATION WITH MUTT
+
+mutt-notmuch can be used to integrate notmuch with the Mutt mail user agent
+(unsurprisingly, given the name). To that end, you should define the following
+macros in your F<~/.muttrc> (replacing F<~/bin/mutt-notmuch> for the actual
+location of mutt-notmuch on your system):
+
+    macro index <F8> \
+          "<enter-command>unset wait_key<enter><shell-escape>~/bin/mutt-notmuch --prompt search<enter><change-folder-readonly>~/.cache/mutt_results<enter>" \
+          "search mail (using notmuch)"
+    macro index <F9> \
+          "<enter-command>unset wait_key<enter><pipe-message>~/bin/mutt-notmuch thread<enter><change-folder-readonly>~/.cache/mutt_results<enter><enter-command>set wait_key<enter>" \
+          "search and reconstruct owning thread (using notmuch)"
+
+The first macro (activated by <F8>) will prompt the user for notmuch search
+terms and then jump to a temporary maildir showing search results. The second
+macro (activated by <F9>) will reconstruct the thread corresponding to the
+current mail and show it as search results.
+
+To keep notmuch index current you should then periodically run C<notmuch
+new>. Depending on your local mail setup, you might want to do that via cron,
+as a hook triggered by mail retrieval, etc.
